Bruno Mars excitedly tweeted last night, “I played a bunch of bars all over L.A but this weekend I get to play the Gibson amphitheater in universal studios,” prior to his show with fellow retro-inspired musician Janelle Monae at Universal City’s Gibson Amphitheatre. With the help of the “Lighters” singer’s hooligans, the “Tightrope” songbird’s Arch Orchestra, the dynamic duo were able to turn Los Angeles into Wondaland. Check out highlights from their first of two shows in the City Of Angels and check out Bruno’s incredible live rendition of “Top Of The World” here. (Ed note: Holy Cow! Those horns!)
